>>When people teach Haskell, it typically isn't to give them "real world
experience", but to teach them an interesting programming language and all
the great computer science it leads to. Types, laziness, higher-order
abstractions are the hard bits to learn, not a string-processing API.
If people want to learn how to deal with unicode correctly, I can think of
several better places to learn about it than a Haskell course. I don't
think it's condescending or impractical to focus on the things that make
Haskell unique, rather than teaching a unicode-correct API that could
conceivably be written in any other language. Learning that real human text
cannot be treated just an independent list of characters is something that
takes minutes to hours at most: someone tells you that there are all sorts
of exceptions to the list-of-chars paradigm, and then you read an article
or two on the language-specific difficulties, learn to use specialized API
functions, and then you get on with what you were actually trying to do.
So I think saying that ignoring unicode-correct strings a complete failure
and waste of resources is a bit hyperbolic, honestly.
